I have an exposed ceiling with 2x6 Tongue & Groove, with a chamfer detail. The basic profile looks exactly like the T&G you'd buy at home centers and lumber yards.
But my ceiling was made when lumber had different dimensions. The stuff you buy now is too small by around 1/16th of an inch. The depth (the 2 inches) is less of an issue, but the width (6 inches) is a real problem because I'm trying to replace a section in the middle of my ceiling, leading to gaps.
I'm considering cutting my own 2x6 T&G with chamfers to match the existing roof. I'd cut it out of 2x8s.
I'm pretty confident I could cut the tongue and the groove with either a table saw or a router table. But I'd appreciate advice if that's accurate.
I'm not confident at all how to cut the chamfers. Can those also be cut with a table saw, or would a table saw end up splintering out lots of materials? Would I use a router table to form the chamfers? (and if I do that.. .should I just cut the tongues and grooves with a router table as well).
